password protecting a dvd/cd disk

Hello. I am looking for software to protect a dvd or cd from being opened/viewed/edited altogether. Something that when you put the disk in the cd/dvd drive, it won't even allow you to view the contents unless you enter a password. Pretty simple I guess, but I need it to be secure. I've tried a few programs, but they weren't what I was looking for (even though I believe this is a simple task). Any suggestions? Thanks!

Oh yes, I use winXP, but I need the secure disk to be unreadable across any platform.
